The output of the DIRECTORY command depends on the volume format
    and on certain formatting qualifiers and defaults. The following
    are the formatting qualifiers:

    /ALL        /BLOCKS   /BRIEF
    /COLUMNS    /DATE     /FULL
    /OCTAL      /OWNER    /SIZE

    The files that are listed always appear in the order in which
    they appear in the volume directory or the order in which they
    reside on a magnetic tape.
